Introduction

The digital life cycle management starts from the point an item is created or selected for digitization (if not born-digital), continues through image cleanup, metadata capture, and derivative creation, and extends to ensuring long-term access. The two aspects of digital library data quality are the quality of the data in the objects themselves, and the quality of the metadata associated with the objects. Metadata errors occur in a variety of forms, but when errors exist, in whatever form, they affect discovery, access, use, and long term management of the resources.
